Troubleshoot EOF Errors in Docker Push to AWS ECR

If you have been running into EOF errors while pushing Docker images to AWS ECR, you have come to the right place. This error usually lets us know about an unexpected termination of the upload process. It can be due to different issues.

Common Causes and Solutions

• First, make sure the machine has a stable internet connection. Also, check that the ECR endpoint we are using is correct and accessible. Additionally, make sure there are no firewall restrictions blocking the communication.
• Then, make sure the AWS credentials are configured correctly using `aws configure`.

  We also need to confirm that the IAM user or role has the necessary permissions to push images to ECR. The `AmazonEC2ContainerRegistryFullAccess` policy is often sufficient.
  We can ee-authenticate with ECR using `docker login your-ecr-registry`.
• Now, check if the ECR repository exists and if we are pushing to the correct one.

  We can verify if the IAM user or role has the required permissions for the specific repository.
• In some cases, large image sizes can cause issues. We can split the image into layers or optimize it. Furthermore, verify the integrity of the Docker image. Rebuilding it might resolve the issue.
• Then, check the AWS status page for any reported issues with ECR. We can restart the Docker daemon in case of any problems. Also, make sure the system has enough free disk space for the push operation.

Troubleshooting Steps

To effectively troubleshoot and resolve EOF errors, follow these steps:

1. First, examine the Docker daemon logs for more detailed error messages.
2. Then, use the AWS CLI to push the image and see if we run into similar issues.
3. Next, create a smaller Docker image to isolate the problem.
4. Some network or transient issues can be resolved by increasing retry attempts.
